:-/thanks but what i needed to know is how much to put in my sump i have 200p in my 75g tank so all i could do is fill the sump with as much as it would hold in the box

 

If you are putting LR rubble in where the bio balls came out just fill it up to the top of the container. You need to make sure they are not submerged in water, the water just needs to trickle over it just like the bio balls.

 

thanks otty thats what i did some r in the water all the way but most is out thanks for the info

 

i have a 75g reef with a wet/dry that has L/R upto the water line in the sump then bioballs ontop of that upto the strainer. quiets the water and is the best of both worlds.

 

Or completly submerged, depending on your school of thought.
